DEEP VEIN THROMBOSIS (DVT)

DVT occurs when a blood clot forms in a deep vein. Most commonly this happens in the veins of the lower leg, calf, but can spread up to the deep veins in the thigh. It has been known to develop in other deep veins, such as in the arm.

Not all blood clots that occur in DVT caused symptoms, your body is very complex and dynamic and is able to gradually break these clots down without any long-term effects.

Larger clots may cause complications and block the blood flow in the veins. This will create symptoms such as;
-Pain in the affected area, which may get worse when standing or walking
-Reddening of the affected area
-Swelling, not to be confused with long-haul flight swelling as often encountered

People over 40 years of age who are tall and or obese, or those people who are in mobile for long periods of time, such as those on long-haul flights or who have had an operation are more likely to suffer DVT.

Other predisposing factors can be a family history, inherited conditions, certain blood diseases, cancer or cancer treatment, circulation problems all those people who may have suffered an injury or undergone surgery.

There is evidence that travelling for long periods of time such as on long haul flights increases the risk of developing DVT. Long haul flights may be considered four hours or longer. The reason appears to be prolonged immobility, which may also occur on long car, bus or train journeys.

You may consider you are at high risk if one of the above factors is present. There are some simple measures you may undertake to reduce the chances of developing DVT:
-Exercise the muscles of your lower legs regularly, take short walks, regularly bend and straighten your toes, legs and ankles
- Wear loose fitting clothes
- Remain hydrated and take plenty of fluids
- Do not consume alcohol or caffeine
- Do not take sleeping tablets
- Consider wearing compression stockings
